摘要: Abstract The retention of lead by a very fine sandy loam was investigated. Aqueous concentrations between 10 and 1000 mg/L soil ranging from to 167 g/L were used. Lead the strong function pH. width pH—adsorption edge decreased with increasing concentration. Experimental results modeled using Langmuir, Freundlich, BET isotherms. Only Langmuir Freundlich isotherms successfully represented experimental results. role surface precipitation assumed be small because failure isotherm adequately predict metal retention. provided best fit maximum concentration usually not observed. parameters varied in way that suggested average binding energy distribution bond strengths increased expressions determined this study can used as source-sink terms i...
